INSULATOR-SUPPORT FOR ELECTRIC CONDUCTORS.
SPECIFICATION forming part of Letters Patent No. 396,196, dated January 15, 1889. Application filed December 29, 1886. Renewed May 4, 1888. Serial No. 272,858. (No model.)
To all whom, it may concern.-
Be it known that I, LEO DAFT, a subject of the Queen of Great Britain, residing at Plainfield, Union county, State of New Jersey, have invented certain new and useful Improvements in Insulator-Supports for Electric Conductors, of which the following is a specification.
My invention relates to that class of supports for electrical conductors mainlyintended for overhead conductors for tramways, &c.; and my invention consists in means, fully set forth hereinafter, for connecting and insulating the supporting-hangers and for clamping the conductors to the hangers.
In the drawings, Figure 1 is a side elevation in part section, showing two supportinghangers for the parallel rails of an electrical conductor. Fig. 2 is a section on the line 1 2, Fig. 1, looking in the direction of the arrow.
\V represents any suitable supportas, for instance, one of the cross-bars or sleepers of the support of an overhead electrical conductorand 0 represents the hanger pendent from said support \V, which hanger is turned up at the end to support the heavy electrical conductor 3, which, as shown, is a round wire or bar, but may be otherwise con structed.
In order to suitably suspend the hanger from the support WV, I bolt to the under side of the support, by means of bolts G or otherwise, a plate, A, connected to or forming part of a bonnet or hood, J, the whole being formed of cast-iron or other suitable material.
The upper end of the hanger O is provided with a cross-head, 5, or otherwise constructed so as to receive securing-bolts D D, which pass through openings 00 in the cross-head, which openings are larger than the bolts to prevent contact between the latter and the cross head, the said bolts extending into threaded openings in the plate A, and also through washers P, arranged between the heads of the bolts and the cross-head, and through a plate or sheet, B, the latter and the washers being of vulcanized fiber or other suitable non-conducting material; and metallic washers 7 may be placed between the washers P and the heads of the bolts, so as to prevent the washers P from being wounded by the turning of the bolts. By this connection of the hanger with the support V, I
firmly secure the hangerto the said support, so as to support the conductor in such man ner as to resist the strains imparted to it by the traveling thereon of the moving trolley, and at the same time I effectually insulate the hanger from the parts to which it is connected and from the connecting-bolts and protect the insulating material from storms, so that it will remain in a dry condition.
In order to detachably but firmly connect the conductor 3 with the hanger, 1 construct the latter with a stationary jaw, 4, and a movable jaw, 5', each curved or recessed, so that when the jaws are brought together they will form a socket to receive the conductor, and in which it is securely clamped, the jaws being perforated for the passage of transverse bolts (i,by means of which the movable jaw may be brought forcibly toward the stationary jaw and against the conductor in the socket. Vhile the conductor is thus securely fastened, it may be readily detached at any time by simply loosenin the bolt (3.
\Vhile l have shown the parts above described as constructed to support two parallel conductors, 3 3, the same parts may be used in connection with a conductor consisting only of a single rail or rod; but in either case the conductor is firmly supported, effectually insulated, and is held in position upon the upturned ends of the brackets in such manner as to expose a continuous unbroken upper surface for the support and guidance of the trolley.
It will be understood that the forms of the parts may be varied according to the particular character of the conductors and the positions in which they must be supported.
\Vithout limiting myself to the precise construction and arrangement of parts shown, I claim 1. The combination, with an overhead electrical conductor, and with a bracket supporting the same, of an overhead support, a bonnet secured to said support and receiving a cross-head of the bracket, and fastenings extending through the cross-head into the honnet and through insulating material between the fastenings and the cross-head and between the latter an (1 the bonnet, SllbStflllhiflHY as 501 In testimonywhereofIhave signei'linynzune forth. to this 1 eeiiieui ion in the presence of two sub- The combination of the support,pendent scribing witnesses. bonnet, bracket supporting a conductor and I provided with a cross-head having openings :1, LIN -'I)Ah"l.
